The purpose of this study has been to test public perceptions of both scenic quality and recreational acceptability of southwestern ponderosa pine forests exibiting one-to-five years of recovery from both light and severe fire. Public fire-effects information documents were also constructed and tested. Appropriate ponderosa forest areas in Arizona were selected and randomly photographed. Population samples, drawn from Tucson, Arizona, first read fire-ecology or "control" information brochures and then rated forest scenes on 1-to-10 scales for scenic quality and for acceptability for selected forms of outdoor recreation. Respondents finally answered a short fire-knowledge, fire-attitude questionnaire. Ratings were subjected to SBE analysis (Daniel and Boster, 1976), and analysis of variance was applied to both ratings and questionnaire results. The clearest distinction drawn, for both scenic quality and recreational acceptability, is between light-fire and severe-fire effects. Light fire improves scenic quality for a 3-to-4 year period, while severe fire seriously detracts from scenic quality for an unknown length of time exceeding the 5-year period tested. Recreational acceptability is differentiated according to the recreational activity selected: camping is nearly twice as sensitive to severe fire effects as scenic quality, and is somewhat disrupted by light fire effects; picnicking is second-most impacted by severe fire effects; hiking or backpacking is affected by severe fire to about the same degree as scenic quality; nature study is least affected. Picnicking, hiking and nature study are not significantly affected by light fire. Provision of fire-effects information does not significantly affect scenic or recreational evaluation of forest burn areas. The fire-effects information brochures produced general "halo" effects on both fire knowledge and fire attitude in the groups sampled. Fire knowledge shifted toward the expert position that fire effects are less severe than generally believed. Fire attitude shifted toward the expert position of greater tolerance for fire in ponderosa ecosystems. Results show prescribed burning as generally acceptable. The results of this study demonstrate distinctions between affect (perceptual evaluations) and cognition (questionnaire response). Scenic and recreational evaluations emerge as clearly distinct entities.

This thesis examines the Schultz Fire as a case study to explain the complex history of fire suppression management in America’s forests, and to gain further understanding of how management practices have affected the increase in fire severity levels and how forests respond to such a disturbance. The thesis objectives were: (1) to analyze the causes of the fire severity of the Schultz Fire, especially: topography, fuels, or weather; (2); to examine the possible correlation between fire severity and tree density; (3) to investigate whether post-fire species richness was related to fire severity two years after the Schultz Fire; (4) to investigate whether post-fire plant species richness, plant cover, and tree regeneration was related to fire severity two years after the Schultz Fire; and (5) to interlink and convey how these factors relate to the history of fire management and policy and public perception. The history of fire related policy and management has significantly changed the dynamics of America's national parks and forests. Understanding the larger context of this history, both of national fire management and of the effects of language and perception on policy and public reaction, is part of understanding the Schultz Fire as a whole. Based on modeling, high winds combined with the presence of high surface fuel load were the main causes of the Schultz Fire's high fire severity levels. As fire severity increased there was a statistically significant increase in species richness. Severity level had little variation on percentage of cover by plants. No statistically significant relationship between tree density and fire severity levels was found. These findings underline the need for fuel treatments in southwest Ponderosa Pine forests, and effective cooperation between communities, managers, and ecologists. The Schultz Fire serves as an example in understanding the intricacies of how history affects the present and future of fire management. How fire has been managed and portrayed in the past has left an indelible mark on how fire is presently viewed. Without a clear understanding of the history of fire management and the role of fire in the ecology, future policies towards fire will be unable to account for and manage for the diversity of ecosystems and fires effects on those ecosystems across the United States. / Graduation date: 2013
